Delicious Overnight Breakfast Casserole with bacon, green onions, bell peppers, and cheese.


  • 12 slices egg bread or any type of bread will work, cubed
  • 12 slices crispy bacon crumbled (or 1 cup diced ham)
  • 3 green onions sliced
  • 1/2 red bell pepper finely diced
  • 4 cups grated cheese cheddar works well
  • 6 eggs
  • 3 cups milk
  • 1/2 teaspoon each dry mustard salt & black pepper


  • Cube bread and leave out overnight or place in the oven at 300 degrees for about 10 minutes to dry slightly. (Do not brown or toast it).
  • Combine eggs, milk, & seasonings.
  • Layer 1/2 of the cubes in a greased 9×13 pan. Top with 1/2 of the bacon, green onions, red peppers and cheese. Repeat layers one more time.
  • Pour egg mixture over top. Cover and refrigerate overnight (or at least 3 hours).
  • Remove from fridge and let sit on the counter while preheating the oven to 350 degrees. Bake covered with foil 45-55 minutes or until a knife inserted in the center comes out clean. (If you are baking 2 pans increase cooking time to 60-80 minutes).
